MSG Equipment specialists are very serious about the restorative process of the unit. There is a specific restoration procedure for each unit.
Main failures of Ford Focus 3 steering rack
Parts of the steering mechanism constantly come under increased loads. Water and road dust often get onto the steering rack, and rubbing elements are subjected to wear.
The cause of knocking in the mechanism is a gear pair performance, the natural wear of the bearings.
Ford Focus 3 steering rack often fails if the dust boot is broken. Water and dust get onto the shaft causing corrosion. To prevent damage of the mechanism, it is required to monitor dust boots, check the power on the electric motor.
There are frequent causes of the steering rack breakage: moisture, mechanical impact, break the wire, software failure, torque transmitter failure, power loss.
Worn gear pair leads to a backlash in the steering wheel, the car becomes uncontrollable.
Signs of the steering rack breakdown:
- Steering rack self-locking. Such a breakdown is often associated with damage of the dust boot. Dirt gets into the teeth, which together with moisture is converted into an abrasive mass that “eats” the teeth.
- More steering wheel turning force is required. The cause of breakage is belt wear in shunt package mechanisms. In these situations, the belt should be replaced.
- Mechanical noise at the time of steering input. The cause of noise in the steering wheel area, most likely, is the electric drive. A mechanical hum points at bearing wear. If the electric drive is supposed to be dismantled, then a full range of activities must be obeyed.
- Power steering reacts to steering wheel rotation with delay. Such a breakage comes out because of sensors’ or ECU fault.
Specialized service centers for high-quality diagnostics use MS561 controller. MS561 device is used to test the operation of EPS units.
The biggest advantage of the EPS controller is OBDII connector, which is required for connecting various diagnostic scanners to it. The controller firmware and units’ database are updated via the Internet, that let equipment continue to be relevant for the longest time.
